How to obtain Vista Edition programmatically?

Question

How to obtain Vista Edition programmatically, that is Home Basic, Home Premium, Business or Ultimate ?

Answer 1

MSDN gives extensive answer:

Getting the System Version

Answer 2

Environment.OSVersion

Answer 3

Brilliant! This is just what I need as well. Thanks aku.

edg: Environment.OSVersion contains a version string but this doesn't generally give enough information to differentiate editions (also applies to XP Home/XP Pro). Also, there's the risk that this string will be localised so matching on it woudn't necessarily work.
